Experiment 4:
Quantitative Determination of Sulphate by Gravimetric Analysis
Synopsis:
This experiment aims to determine the amount of SO42- via the gravimetric method. By this way, we will be able to familiarize ourselves with the procedures of gravimetric analysis. Precipitation of BaSO4 is done by acidifying the diluted sulphate solution and then adding BaCl2 solution after heating it for some time. A test for complete...

Is H20 Bad for You?
Abstract:
In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were
four infants affected by this cluster. The families from the infants would collect their
water from wells. We have to determine what’s the source of the high levels of nitrites in
the water. The four sources that could be the point of contamination are a new
subdivision, textile plant, an organic farm,...

...This means that all of the HA will be neutralized, causing the pH to change. Because of the rapid pH change around the equivalence point, the titrant has to be added in lesser and lesser amounts as we approach the equivalence point.

Introduction
In the banana oil lab we began with isopentyl alcohol + acetic acid  isopentyl acetate + Water. We needed for this experiment a hot plate, clamps, pipette, 5mL vial, caps, hoses and a thermometer. Upon starting, our group set up an open system experiment that allowed gases to be released to avoid pressure build up. We mixed together to...

...body, as well as identifying the subcatergories of tissue types while observing them through the microscope and diagrams, and be able to explain the location and function of the tissue types in the body.
There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used.

...as sand are formed from physical combination of various substances, and are called mixtures. Mixtures can be classified into homogeneous and heterogeneous. The purpose of this lab is to learn how to separate individual components from a mixture through decantation, filtration, distillation, and crystallization.

Introduction: In a chemical change, the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products.
In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe...
